A company asks you for an electronic signature
It may happen that an organization has already determined which signing software you must use. For example, you have been able to easily sign a digital purchase agreement from a real estate agent with Vidua for several years.
In some situations, you have the option to select how to place your qualified signature, allowing you to choose Vidua as your provider. In other instances, where only a qualified signature is necessary, you can simply use Vidua Signing (see below). This way, you can safely sign a government tender, for example.

Can I sign a government procurement with Vidua?
Often yes, but not always. The signature requirements set by the receiving party can vary. To determine if you can sign with Vidua, the following is important:
The Certificate
When registering, you receive a PKIoverheid certificate linked to your Vidua profile. This certificate is suitable for placing qualified electronic signatures at the highest level of trust.
The Signing Software
To sign using Vidua, you will need signing software.
Make sure that:
- The signing software supports the file format to be signed (e.g., PDF or XML);
- The signing software supports the required type of signature (e.g., PAdES B-B);
- The receiving party accepts the (electronic) signature.
Authorized Signatory
The procuring entity wants to ensure that the signer is authorized. Especially when bidding with equal partners, each partner may need to sign individually. Ensure that everyone who must sign is also registered with Vidua.
For procurement, you want to be certain that you meet the requirements. We are happy to advise if you are unsure. If necessary, we can prepare a verification question for the information note together.
